Unlike most homes, movie theaters use sound absorbing materials on walls and ceilings. The result is that the sound reaching your ears is the sound wave produced by the speakers rather than reflected off the walls. Yamaha has created waveguides that greatly reduce reflected sound and increase the proportion of directly generated sound waves reaching your ears. The result is a clear and precise sense of sound direction and placement.
Yamaha has chosen to ensure optimum sound quality by internally wiring some of the components with Monster Cable™. This ensures a clean, clear signal from the crossover network to the speaker driver.
Yamaha's matching speaker stands provides the solid footing necessary for full floor contact, enhanced stability and minimal vibration resonance. The stands also provide an attractive counterpoint to the cabinet.
The speaker is magnetically shielded, so it can be placed on a TV or video monitor without degrading the picture via stray magnetic fields.
To further maintain signal purity, Yamaha provides bi-wiring capability for the NS-555 speakers. There are separate +/- terminals for the woofer(s) and other driver(s). The separation reduces modulation distortion and better sound quality.
The EF series speakers are enclosed in an elliptical form cabinet with a high gloss black piano finish, which provides solid construction with minimal sound diffraction.
New grille design and grille cloth provide an attractive and acoustically transparent protective cover for the drivers.
